Dissociative recombination of electrons with ArXe{sup +}

The authors have recently reported calculations for low-lying excited state potential curves of XeAr, and they have used these potential curves for coupled channel scattering calculations of inelastic scattering of Xe. A typical process is Xe + Ar {yields} Xe + Ar. Dissociative recombination (DR) corresponds to different arrangements of the same particles. DR may be written ArXe{sup +}+e{yields}Xe+Ar. Because the same Hamiltonian describes inelastic scattering and DR, much of the authors earlier work can be extended to provide the potential curves and coupling matrix elements necessary to treat DR. Part of the task is to determine the energies of very highly excited states of Xe Ar; this can be done by using Multichannel Quantum Defect Theory (MQDT) to extrapolate the authors earlier results. Preliminary results will be reported.
